National Postal Museum: Exhibits, Hours, and How to Visit

Do you love stamps? Then you’ve come to the right place!

The Smithsonian National Postal Museum in Washington D.C. houses the largest collection of stamps and postal objects in the world!

This includes vehicles used to transport the mail, mailboxes, meters, and postal materials that predate the use of stamps. Visitors can walk along a Colonial post road, ride with the mail in a stagecoach, browse through a small town post office from the 1920s, and receive free stamps to start a collection.

Highlights include 3 vintage mail planes; a stagecoach; a 1931 Ford Model A postal truck; a replica of a railway car; and the William H. Gross Stamp Gallery.

Museum Highlights

The National Postal Museum is more than stamps – it’s trains, planes, and surprising stories from America’s communication history.

World’s Largest Stamp Gallery

The National Postal Museum houses the world’s largest stamp gallery. It includes rare pieces and stunning designs. Visitors can trace the journeys of historic letters, create a virtual stamp collection, and design their own stamp.

I love stamps, so I was enthralled. Check out all of the stamps below!

The World’s First Postage Stamp

On May 1, 1840 Great Britain issued the world’s first postage stamp. Called the Penny Black, the stamp revolutionized postal services worldwide.

Before postage stamps, mail recipients usually paid the postal fees. Sometimes they refused to pay. Fees often varied according to distance within a single country.

With the Penny Black, mail could be sent anywhere in the United Kingdom for a standard fee. Senders prepaid the fees; the stamp provided proof of payment. The postage stamp was very popular with a British people. Use of the mail soared.

The First U.S. Stamps

The United States released its first two postage stamps on July 1, 1847. The 5-cent stamp featured Ben Franklin, the nation’s first postmaster general. The 10-cent stamp featured George Washington, the first U.S. President.

Search all U.S. Stamps

There is a machine where you can search all of the stamps from a specific year or subject. For example, Cats.

Oops! The 1918 Upside Down Stamp

In 1918 the U.S. Post Office accidentally printed and sold a sheet of 100 stamps with an error. It featured an upside down blue plane with a red frame. It is the most famous U.S. stamp and one of the world’s most famous printing error.

The Pony Express

No story of American mail delivery is more famous than the Pony Express. The service lasted for just 18 months from April 1860 – October 1861. But it became one of the most legendary chapters of the American West.

The route stretched nearly 1,966 miles between St. Joseph, Missouri, and Sacramento, California. Riders followed a strict relay system, switching horses every 10 miles at 165 stations. Each man typically rode 75-100 miles before passing along the mochila (the leather mail pouch) to the next courier.

Mail reached California in just 10 days during summer and 12-16 days in winter. In 1860, that was astonishingly fast!
